rrcxnn STICK FOR LOOMS.

Application filed August 7,1925. Serial No. 48,856.

a device which may be readily removed or replaced in a holder which is normally oscillated for causing thepickerstick to drive the shuttle transversely of the loom.

A further object of the invention is the provision of a stick which is of simple yet durable construction and which may be read ily replaced when desired by the release of a catch which is adapted to operate to maintain the spring normally in longitudinal alinement with its holder.

This invention will be best understood from a consideration of the following detailed description, in view of the accompany ing drawings forming a part of the specification; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no ma.- terial departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

Figure 1 is a side view in elevation showing a picker stick constructed in accordance with the principles of my invention applied to a loom.

Figure 2 is a vertical section of the picker stick.

Figure 3 is a view in perspective of the picker stick showing the elements of said stick in detached relation.

Referring more particularly to thedrawings, 10 designates a loom having a bearing 11 at its lower end in which is mounted one end 01 a bracket 12. On said. bracket is mounted a rock shaft 13 which carries a socket 14 which receives the lower end of a picker stick which is composed of two members, namely a holder 15 and a removably mounted bar 16. The socket 14 is rockably. mounted on the shaft 13 and is movable between guides 17 on the bracket 12. As shown more particularly in Figures 2 and 3 perforations 18 are provided for bolt ing the holder 15 to the socket 14.

Intermediate the ends of the channel shaped holder 15 are provided a plurality of perforations 19 which are -a-dapted to receive pins 20 for engaging opposite edges of a strap 21 which is connected to an operating means 22 at its inner'end and at its outer end the strap engages aroundithe.

holder 15. The pins prevent slippage ofthe strap of the holder. A plurality of the perforations 19 are provided so that the outer end of the strap may be adjusted to the various elevations along the holder so that the holder may be accommodated to looms of various sizes and makes. The

strap 21 is of the usual type and forms apart of the loom construction. 7

The bar 16 is normally flat and has a reinforcing rib 23 at its periphery. Intermediate the ends of the bar and along one edge is provided a notch 24; Said notch 24 is adapted to be engaged by a pin 26 secured in the upper end of the holder 15 and adjacent the rear wall 27 of said holder.-

Ears 29 project from the edges of the channel shaped holder 15 adjacent its pin 26 and aid in holding the bar 16 from displacement from the holder during sudden ars to the holder.

A barrel 34 is integrally formed with the holder 15 adjacent its upper end to receive a spring 35. The inner end of the spring engages a recess-'36 in the lower end of the bar 16 while the outer end of thespring is engaged by an internally threaded cap 37 which is screwed upon the external threaded barrel 34. The adjustment of the cap varies the tension of the spring 35 while the spring aids in maintaining the lower end of j the bar in tight engagement with the back 27 of the holder 15.

The holder 15 is rocked by the strap 21 in the usual manner and the bar normally strikes one end of the shuttle 38 for driving the shuttle transversely of the loom and through the track 39.

B the construction just described, it will be seen that the bar 1.6 may be readily removed from the holder 15 when desired, by forcing the said bar inwardly from the holder so that the notch 24 is released from the pin 26 and then exerting an upward pull on the bar which will release the. spring 35 from the notch 36 in the lower end of the said bar. As the free end of the bar strikes the shuttle, the bar may be forced slightly outwardly against the tension of the spring 35 so that the bar is cushioned at each stroke in order to prevent injury to the stick and its associated parts when in operation.

Each of the ears 29 are provided with perforations 40 having offset or key slots 41. A pin 42 is received by the perforations 40 and keys 43 on the ends of the pins are passed through the slots 4]. so that when the pin is rotated the keys will engage the ears at points from the slots and thus the pin will be retained against loss. The pin 42 preventsdisplacement of the bar 16 from its holder.

What I claim is:

1. A picker stick comprising a hold-er and a bar removably mounted in the holder, said bar being provided with a notch, the holder having a'pin adapted to be received by the notch in the bar, and means for retaining and cushioning the lower end of the bar in projecting laterally therefrom, and a spring in the barrel in engagement with the lower end of the bar.

3. A picker stick comprising a holder and a bar, said bar being provided with a notch on one edge, a holder for the bar provided wit-h a pin adapted to be received by the notch in the bar, said holder being provided with a barrel projecting outwardly, said bar being provided with a second notch along its other edge, a spring in the barrel having 40 an end in engagement with the second notch in the bar and a pin removabiy mounted in the holder and engaging an edge of the bar.

4. A picker stick comprising an elongated bar having a notch formed along one edge, a channel-shaped holder to receive the bar and provided with apin adapted to be received by the notch in the bar, a barrel projecting laterally from the holder and connected to the side edges of the channel shaped member, a spring in the barrel, a removable cap threaded onto the free end of the barrel. and adapted to be adjusted for 'arying the tension of the spring, said spring adapted to have its inner free end in engagement with the lower end of the bar for cushioning said end of the bar.
